WILLIAM H. RUSSELL, OF ST. CLAIR, PENNSYLVANIA.

CHARGE-HEATING ATTACHMENT FOR- EXPLOSIVE-ENGINES.

Application filed December 3, 1913.

To all whom it may concern Be it known that I, WILLIAM H. RUssELL, a citizen of the United States, residing at St. Clair, in the county of Schuylkill and State of Pennsylvania, have invented cer tain new and useful Improvements in Charge-Heating Attachment-s for Explosive-Engines, of which the following is a specification.

My invention relates to explosive engines, and it consists in improved means for utilizing the exhaust to heat the inflowing charge as fully described in connection with the accompanying drawing and specifically pointed out in the claim.

Figure 1 is a side elevation showing my invention applied to an explosive engine of known type; the latter, as Well as the ordinary carbureter employed, being just sufficiently indicated to make clear the application. Figs. 2 and 3 are sectional views on the line 22 and 3-3 respectively, of Fig. 1.

The engine 1, as indicated, is of the ordinary four-cylinder type, having exhaust outlets 2, 2, 2, 2 connected to a single exhaust pipe 3, and inlets 4, 4 each of which leads to two adjacent cylinders having their centers at 6, 6, 6, 6. The exhaust pipe 3, as shown, is formed with a return bend 5 at one end, which is adapted for connection to my specially formed inlet-pipe attachment as hereinafter described.

This attachment comprises, as shown, a main inlet-pipe 10 connecting the engine inlets 4, 4, and an integrally formed branch 11 having an outer-end portion 12 adapted for attachment to an ordinary carburetor 9 from which it receives the charging mixture. Intermediately this branch 11, 12, is enlarged to provide an intersecting transverse exhaust passage-way13, which terminates Specification of Letters Patent.

lPatented Sept. 14, 1915.

Serial No ceases.

at one side of the branch 11 in a suitable It will be readily seen that the very simple and inexpensive construction described provides for preheating the inflowing charge from the carbureter, by passing it completely around and in intimate contact with the heated walls of the exhaust passage 13, while at the same time providing an absolutely free exhaust discharge.

What I claim is In combination with a carbureter and an explosive engine having exhaust and inlet ports and an exhaust pipe connecting said. exhaust ports formed with a return-bend, a charge-heating attachment in the returnbend portion of said exhaust pipe, said attachment comprising a separate integrally formed charge-and-exhaust connection having a transverse unobstructed exhaust-passage portion, and an annular charge-passage portion surrounding the same, exhaust pipe connections at opposite ends of said transverse portion, and cylinder inlet-port connections and a carbureter connection at the opposite ends respectively of said annular charge-passage portion substantially as shown and described.

In testimony whereof I afix my signature in presence of two witnesses.

WILLIAM H. RUSSELL.
